Why does Unity not import materials from DAE file ?

I’m trying to upload a DAE file (Exported from SketchUp) into Unity3D.

It imports the meshes, but all of them are grey. I guess it imports materials too, but all materials become grey or something. Here are the pictures of what I mean :

SketchUp :

Unity :

How can I import the materials with colors (or textures) ?

Unity takes the material info on import as well, it just doesn’t bring in the maps at the same time (as this constitutes a separate import)

just import the texture map as a new asset

then assign the map to the material slot of the texture that is on the DAE

if you have several maps/material on one model then you will have to repeat as necessary
